When it comes to trimming hard-to-reach areas, the weed eater truly is a valuable piece of lawn equipment to own – and ensure your lawn looks its best.

That is, as long as your string trimmer works correctly and delivers a fresh trimmer line when you need it!

Never fear; today, we’ll show you how to change the weed eater string easily and quickly.


Three (3) Types of String Trimmer “Heads”

Before changing your line, it’s essential to understand the three (3) primary Types of weed eater trimmer “heads.” The trimmer head is the part of the weedeater that holds the “spool”, and trimmer line.

Let’s first determine which one you own – or maybe the one you’d like to own!

1) Fixed Line Trimmer Head

The first weedeater trimmer head type we feature is the fixed-line trimmer head. This type of trimmer head uses three or more short pieces of pre-cut trimmer line, usually held in place with locking tabs on the trimmer head.

There are a few different varieties of this design, and it is a little more expensive to own because it requires more frequent line replacements than bump-feed trimmers. However, If you’re looking for one of the easiest ways to replace the trimmer line – this is it.

The Plus side, however – is almost zero downtime. You change the tab lines once every few months. No tangles, spool changes, etc., and the line used is typically heavier.095 gauge trimmer line. 

The Fixed-Line Head also design provides a very aggressive cutting head for mowing down tough weeds or grass.


2)  Bump Feed Trimmer Head

Next up is the bump-feed trimmer head, which houses a trimmer line spool. The spool usually holds 20-30ft of string trimmer line. When you “bump” the head against the ground, it automatically feeds a short line section out and trims it to length.

The bump-feed trimmer is the most common weed eater head type and is usually found on less expensive trimmer models.

It is considered the most difficult to reload and use for most people. Very few people reload the trimmer head with a new line but instead opt to replace it with a new pre-loaded spool.

We recommend looking at one of the “replacement heads” such as a fixed-head or speed-feed head –  to replace your bump feed head.


3)  Automatic (Speed-Feed) Head

Finally, there’s the Automatic (or speed-feed) head.  Our #1 First Choice in New or Replacement Trimmer Heads.

The Automatic (speed) head combines a more giant spool and a bump-feed head with the convenience of a super easy changing system. It’s brilliant and is considered the go-to trimmer head design for most professionals.

The Speed Feed head allows you to feed in long lengths of heavy gauge .095 trimmer line – usually about 20ft. Long.

Once the trimmer line is inserted, wind it onto the spool with a quick ratchet action by hand.

An automatic trimmer head makes it very easy to load many trimmer lines without tangles, snares, or snags. This design can be found on high-end trimmers and is usually considered the best type of trimmer head for most users. 

If you afford it and have a larger yard, this is highly considered the best replacement trimmer head to own.


How to Change String Trimmer Line on “Fixed-Line” Trimmer Head

Step 1: Remove Old Line Remnants

Old trimmer lines on fixed-line heads gradually wear down to very short nubs, but the trimmer will have a residual line when you change it.

The way you remove it depends on the exact configuration of the head, but it can either be pulled back out by pressing a button to loosen it or pushed through to a hollow center. Once removed, dispose of the old piece of line.

Step 2: Insert New Line

To load a new line, push the new lengths of fixed-line into the holes on the trimmer head, depressing the loading button if your trimmer requires it. You’re ready to get to work as soon as the line is loaded.

Here’s a quick video on “how to change trimmer line on typical weed eater heads, and how to install Fixed-Line Trimmer Head.”


How to Change Line on a “Bump-Feed” Trimmer Head

Step 1)  Remove the Trimmer Cap and Spool

To wind the new trimmer line onto the spool, you first have to remove the spool.

Do this by first pressing down on the spool cap and twisting it counterclockwise to loosen it from the body of the trimmer head.

Once the cap is off, remove the existing spool.

Rewind or Replace?

At this point, you can either replace the old spool with a pre-loaded New trimmer spool. If you’re replacing the spool entirely with a new pre-loaded spool – do so now, then replace the spool cap.

However, If you choose to rewind the existing spool, move on to Step 2 below.

Step 2) Insert Trimmer Line On Existing Spool

First, remove any small amount of remaining trimmer line that is left inside of the existing spool.

To install the new trimmer line onto your existing spool, cut the length of the new trimmer line from a bulk package of the line gauge you want to use.

Thread the line through the guide hole on the side of the spool, then pull it through until each end of your line is of roughly equal length.

Step 3) Wind New Line

Next, you’ll wind both ends of the line onto the spool together. You want to prevent them from crossing over each other, so it’s essential to keep them pulled tight as you wind.

Check the spool for an arrow that tells you the appropriate direction in which to wind.

When you near the end of the line, use the two notches on the side of the spool to hold the two line ends in place.

Step 4)  Reassemble Trimmer Head

Place the spool back into the trimmer head and feed approximately 10″ of trimmer line out of the head.

Once the head is securely mounted, you’re finished.

How to Change Trimmer Line on Automatic-Feed Head

Step 1) Twist Head Cap into the Proper Position

The first step to change the trimmer line on weed eaters with automatic feeding heads is to rotate the trimmer head cap until it is in the correct position to feed the new line.

The correct head “position” can be found – by locating the “Arrow” stamped on both on the body and the cap – then lining them up from across from each other.

You can consult your owner’s manual if you aren’t sure.

Step 2) Feed New Trimmer Line

Once the cap is in the correct position, feed one end of the trimmer line approximately. 20 ft. Long – through the eyelets on the head.

As with the standard bump feed spool, you’ll want the two ends of the line to be about the same length.

Keeping the two lines out of the way, turn (ratchet) the cap on top of the trimmer head to automatically feed the line into the internal spool.

Note: On most trimmers with this head type, you’ll turn the cap clockwise to wind the line onto the spool.

Because Black & Decker manufactures electric trimmers, changing the line is a bit different. Unlike the methods described above, Black & Decker trimmers and most other electric weed eaters are designed to have their spools removed and disposed of.

Once disposed of, they are replaced with new trimmer line spools preloaded with the trimmer line.

To replace the Black + Decker Trimmer line spool, pop the cap off the bottom of the trimmer, then remove the old spool; next, thread the line on the new spool through the eyelets, insert the spool, and replace the bump cap.
